About Maple Leaf

Maple Leaf Design began in 1995 as a cottage industry with a passion for building state-of-the-art radio controlled sailplanes. The team consists of Don Peters and Phil Pearson with over 75 years of combined experience in composite design and construction.

The company's mission is to build the absolute best sailplane models possible. Their design process starts with computer-modeled performance prediction. Airfoils, planforms and moments are then computer-designed and optimized to fit the computer model. Learn more about Maple Leaf Design here.
